.552 Fmi *f i f/{TZ *Chieagrn in the enmity or' @ook and 'State oi? I lliinnis have invented certain new and usei'ul improvements in Cipher 'YlLi/geiifriersv of n'hnh the "ieilnvv'iiil :i speeitieatien.

in my iinited Letters iatent lle. Tlfvissued 19GB, there shown and described an invention the objecty oi? which .is to construct a cipher typeivriting machine that it n auteniatieallyi, the result ot an ari'iitraiv predetermined arrangement of the print-ing eliaraeters in their relation to a given kej; hoard., transt'orin any desired message into a cipher torni inrapahle oi? translation excejit by one having a like nia-shine and. 'poser sing the key or Combination liv which it inaj/ be set to translate th iireviously printed cipher.

The inv-enti also provides one or more character ferme? preferably in the shape or' difks or type wheels, each character forni haring a Series el charactersthereon from 'which a printed i1l eression ma;7 he taken, and eaeh heim provined with means whereby said chale@ :nav he arranged in a predeteri'nined. and arbitrary relation with respective irespect to an arhitr f l zero point, well as to a set of operating keys, the arrangenient of which latter is permanent and. con etant, the reiatiim between the two heirg suela that when a key is actuated, ainother and different character :trein that rep resented iliereon may he printed.

The purpose oit the invent-ion is to so ar-I range the character-smut! keys with respect to each other that when the latter are ac'tnated the result will he an apparent hetero geneousvcoHglon'iera-tion of printed. characterscenstitutingj a cipher, the iranslarion of which can only be made by one haring the key to or a knowledge of the relative @our hination of the printed forms, and having such key the printed forms mayY he arbitrarily re-aeanged to harmonize therewith s0 that the striking of the keys in the order `0i the printed cipher will result in the automatic translation of said printed cipher and the printing of the message in its original form.

The aforesaid invention also provided automatic means for Changing the relation between the characters represented by the keys and those upon the type pecicatien of Letters 'Patent lgrl-@nlgl ffgly 3 j lajlglh Applieaton filed July B. 1910. Serial No. 557x193?.

l provided means for measuring the inter- 'als automatically. wherein' the relation of '.1V 2 L' Lne Characters to the keys could he changed, 'onserulively or otherwise so that Jdie dwe- -pressiou et a given. key would Cause dii ferent Qharaeiers to be printed at diiierent times.

The present"j invention relates more partienlarly though not necessarily to an irn- @rarement on the above referred to 'patent and comprises .means nnerehy unlimited Changes of the printing characters with respeet to the keys may be autoinaticallyv et tested. to not only produce nuniherless Linde eipherahle eiphers, each differing; from the others, but will also produce cipher mes sages which are. of a very complex charac- A further object is to provide an attachment preferably in the form, et interchangeable revolving disks constructed in coperating pairs, one disk of the pain, when. attached to-the machine, being adapted to autimiatieally ei'iange the relationnel' l1-he characters with respect .to the keys to prodnee a einher and the other being adapted to translate the cipher by maternaticiialljyY shifting or changing the rela-tion oi the characters with respect to the keys and in the direction or directions reverse from the respective directions in which the chafa@ 43ers were shifted hy the cooperating disk which produces the cipher.

A further object' is to pifwidev an infr proved disk adapted for aitachinent to Cipher producing machines, which disk is provided Wiih a series of spaced portions adapted. to control or effecty an automat-ie change of the relation of theeha 'eaters with respect to the operating keys.

further abject is to provide ay pair o'i disks of this character, each provided with two or more series olapertares, recesses or depressions, the series being arranged in diti`erent radiiu one series being adapted. to automatically effect a sluiting of the characters withres'peit to the keys'in one diree-4 heing'adapted to shifting .of iihe the coi e responding; series of apertures, recesses, or

The liree end oi." the detent is connected by ineens oil e rod or ber lb to the nsnel releasing lever 4&9, which is in levers Ql. When t e r ys ere at rest und the detent is Yin its norm-1l position, the erin 25 is edei'ited lo engage the detent and prevenl the rotation of the type wheel or ehurncler form end hold it in its normal position. Vlfhen, however, n. hey de* pressed, the delent ie caused to yield or to be moved iloont its point o'ii pivotal support by the upward pressure of the rod or ber 4S so es to move the delent out oit the path of movement oi" the arrnd, thereby permitting the type Wheel or character forni lo make one revolution before it is again nrrested by the detent, which hitler assumes ils nornml position upon the release of the hey.

ln. order to forni a cushion so ne' not to jar the mechanieih end to gradually stop the erm 45 when it strikes the detent, :i enshion is provided for the erin which may be of any construction suitable for the purpose. Suitable end efficient mechanism l'or this purpose comprises e member 5() (see Fig. (5) which is 'pivotally supported by one end as et 51 to the arm l5 und arranged on the side ofthe erin, to engage the detent. 'lhievnieniber 50 is of e length lo extend slightly beyond the lree extremity of the erm l5 and is provided with n. bifurated portion. 52 (see lfig., 9) into which bifureeted portion e projection. o3 on the erin e5 is adapted to extend. n ehi ie member Sie? preferably in the .torni oil e spring, ie provided between the member `mid the "f 'ent fece of the erin and is secured in position against displacement in any eniteble nimmer. This elastic member 54 tends normally to hold the member 50 away from the erin l5 hut is adapted to yield when the member 50 strikes the detent elli and thereby form a cushion to gradually arrest or stop the movement of the erm l5. ".lfhie arrest-` ing movement of the arm 415 is-necessary beore the revol'ution'oi the type wheel or present the desired character et the proper point to enable the usuel impression to -be i teken therefrom.

(Fig. l.) serve to depress the pins operative connection with :1ll` of the keyv corresponding in number character form 3Q is completed, eoes to.

This is `accomplished by Y Achanged with respect to and also the hej.' levers and to hohl both in normal positions. The pins 56 are preferilily .firrane'erl in the are of a circle and attached to the top thirxreot' respectively' are arms 5o. all oit which extend invvzirclll.' toward a common center 'formed liv the shaft 26. A semi-cirerlar guide ring 5G (ieee Fig. 7) is secured to the traine, and thie` ring is provided with a series of vertical slots 5T adapted to' receive the arms 58 and to Serve as guides theretor. The radial posi tion of the several arms thus preserved while thev are free to he moved vertically.

This construe tion preferred in adapting thejnrention to the particular typewriter referred to, although a larger type wheel might he em ployed and the gears dispensed vviti'.; but thie would be. objectionable owing to the. greater Weight :rml momentum.

it will thus be seen from the foregoing description that when a given hey is depressed the arm 41-5 ie released and the type `vheelor character forni iii is caused to revolve by menne oi the spring gears 28 and shaft 2G. until one of the detente 60 is engagefl 13g/.an 'arm corresponding to the key 23 depressed.
